There's a lot of useful info about growing in coco at Coco for Cannabis. He's all-in on using timers, automatic irrigation, and drain-to-waste with lots of runoff 100% of the time. It works really well, but it can be a bit tricky to get dialed in, and dealing with runoff can be a pain (especially if you care about disposing of it in an environmentally responsible way). I'd take his "you need to always water to 20% runoff" advice with a grain of salt; just try to water often enough that salts don't build up too much, and maybe err on the side of feeding with lower EC. Last grow I used automatic irrigation, but aimed for just barely having any runoff, and then hand-watered extra to get runoff once a week, when I felt like dealing with it. Definitely note his advice about
preparing and re-using coco, though. One of the best parts about coco is that you should be able to reuse it for a while.

There are other approaches, such as hempy buckets or bottom-feeding that may be simpler, particularly if you're doing a really small personal grow like I am. There's also an approach that combines them, with zero runoff. I haven't tried that one yet, but plant to try my next full size (not 1L SOG) run that way.

For nutrients, I don't know if it's available where you are, but I've been using Dyna-Gro: Foliage-Pro in veg, Bloom in flower. The only other thing I'd add is Pro-Tekt, a silica supplement that also works well as a pH Up. They're pretty inexpensive, simple to use, buffer pH nicely, great all-in-one option. People have also recommended MaxiBloom and Mega-Crop as other simple all-in-one fertilizers (both powdered). I can't personally speak to those, but worth looking into.

I use this EC/ppm meter and these pH test drops. I haven't tried using a pH meter, because the periodic calibration sounds like more trouble than it's worth. The EC meter and the test drops have worked fine for me, and in coco you'll probably only need to check pH of nutrient mixes, then compare EC going in (feed) and coming out (runoff). For that, the drops and that EC meter work great. (That EC meter probably isn't anything special, most cheap ones are probably fine.)

People will probably also recommend Grow Weed Easy, but some of their info about coco (particularly watering recommendations) is pretty dodgy. If you haven't done a full grow before, they have helpful info about harvesting and curing, though.

Strain recommendations will depend on a ton on personal taste, but I particularly like Mephisto's Fugue State. :) Good luck!

No worries, happy to help.

I've really no idea how many can grow in there tbh man. It is good for upgrading but you've mentioned keeping it warm. So consider this.

Bigger tent means a bigger environment to control, this means more more kit in winter to warm it - probably 2 heaters chewing through electric at a rate of knots. In summer, bigger extraction, either one giant fan or two medium ones. Making sure air current is good with more column fans moving air around etc and of course your air intake fan bringing in the fresh air. Do you see where i'm going wth this? Not so much about height, that is good. It's the floor space that was too much. I don't think a tent you can walk around in would be a good thing in such a cold room. In this case - more space isn't always better. Of course, this is just my opinion.

If you want 4 autos in a tent then go with a more normal sized tent. It's easier to control the environment and still able to handle your plant load. At least that would be my approach to this man.

I don't know any videos i'm afraid. I'm sure there are tons on Youtube - it's a fairly standard practise. Don't cut a hole in the lid though, do it in the side of the pot. Read that guide I sent I the last post - here and it'll tell you it all. I know there are no pictures of it, but it explains the steps. Tons of other tutorials around though man.

Yeah man, you'll be needed a Hygrometer and a Thermometer. I bought one like this.

I've never grown HPS so don't have a light to recommend i'm afraid. Although /u/IdStillHitIt recommended one which looked good.

Thanks! Yeah I had 1x 300w Roleadro LED, but the plant got too big so I upgraded to those 2 COBs a couple months in haha

Now the Roleadro is over a couple cherry tomatoes and peppers that I planted cause why not? The other freebie photo I planted turned out to be a male so I had space

Excited to see how much I'll get from my first harvest! If it's ever ready -_-

I've gotten a fair amount of help from this sub over my grow, Henry has re-assured me quite a few times haha :D

since it's a clone it's not an autoflower so the right subreddit is /r/microgrowery which also has an informative sidebar

if you want to flower it you give it 12 hrs of light a day, otherwise you give it 18. if you flower now you will not get much. you could put off flowering and keep it in veg for as long as you want, trimming it back as it gets leggy.

you don't have enough light to do anything but keep it alive until you get a good light

this one would work
https://www.amazon.com/Roleadro-Plant-Light-Spectrum-Generation/dp/B01HI3AFYM

you can actually get a more efficient light for less money here http://www.ebay.ca/itm/100W-100Watt-High-Power-White-LED-Light-Heatsink-Cooler-100W-LED-Driver-LENS-/262253316319?var=&hash=item3d0f8408df:m:mwpcPILybO0GxGbdS-vIwjg

you could keep that plant alive and in veg until you've got your equipment together. maybe /r/spacebuckets is more your speed than a tent. the sidebar on /r/microgrowery and http://www.growweedeasy.com will help you do that

also you need to pot that thing up 3 weeks ago

Yeah I just said to another guy about how I’ve been meticulously checking each product I’ve chosen and they all seem to cover the nutrients that base nutes use, except instead of adding some A nute and then some B nute (I found A LOT of a/b ones) I’ll be adding a few extra things per gallon, but I’m convinced now that I do need base nutes too. So I’ve found either advanced nutrients ph perfect sensi A/B or this

https://www.amazon.co.uk/gp/aw/d/B00GOI3ULI/ref=mp_s_a_1_1?ie=UTF8&qid=1518058955&sr=8-1&pi=AC_SX236_SY340_QL65&keywords=biobizz&dpPl=1&dpID=51qIqhxEXOL&ref=plSrch

I’ve been hearing good things about biobizz I’m even going to use their soil next time instead of canna (too much wood chip in canna soil

It look like you are doing great! Sometimes hiccups in the process will elongate things but you will learn and, in most cases, do so without too much detriment to your final harvest.

A bit of advice, if I may. Assuming you arent already doing so, grab an inexpensive TDS meter and start measuring/recording the EC of your inflow and outflow fertigation solution every time you feed. Once you start keeping track of these metrics you can stop guessing about whether you are under/overfeeding your gals. Unlike pH meters, TDS meters are not comprised of complex or terribly sensitive components, so spending a lot on a high dollar product is not necessary.

There are general guidelines about ppm ranges for both autos and photoperiods based on where they are in their lifecycle. As long as you keep within those ranges, it's rare to run into nutrient issues.

I also like to read GrowDiaries for the strains I'm growing to see how other folks fared with the same genetics and what pitfalls they ran into in their process.

Good luck with your garden, friend!

/u/henry_haberdasher gave some great advice so I'd say to follow what he said.

When reading yoru post I thought the same things:

• Your tent is bigger then you need (but might be good for expanding in the future).
  
  
• Don't buy that light, it's good for seedlings but not for the whole grow, I'd go with an HPS, or possibly LED but those are more money. I'd get something like this: https://www.amazon.com/HydroplanetTM-Digital-Ballast-Dimmable-reflector/dp/B01AU7QMMW (Personally I prefer Lumatek ballasts but you can shop around).
  
  
• I also have only done a DYI DWC - so you can get the bucket you were looking at and upgrade the airpump/airstone, or it would be really easy to build that yourself.
  
  
• For Training take a look here: http://www.growweedeasy.com/lst

Thanks, this is my first ever grow, I love gardening and didn't want to spend a massive amount of money for my first attempt (all the gear, no idea type of thing).

I spent about 2 month researching strains for cooler environments, and these seeds seemed to be just what I was looking for (though we have had amazing weather this year so far so I could have probably got away with something that likes warmer environments).

at the moment they are 9 weeks from seed and have been in big pots since week 2 I think the pots are fairly big I would guess minimum 7 gallon possibly bigger. They were lST'ed from week 3 and have been fed using a biobizz trail pack

Soil is canna professional

So including seeds my total cost has been about £45

Edit:spelling

Apollo Horticulture makes great tents and products. I'm running a 6in premium carbon filter from them as well. Have both rents connected and it is doing its job just right.
IMO tent thickness isn't needed. Where I live it gets down to the mid 20s. My garage isn't heated and gets too around 50s, and with my lighting, A small space heater, and the tent, I'm keeping a nice 74(sleep time) 78(daylight) at 40% to 50% humidity constantly.


This is one tent I recommend , and my carbon filter

Small tent, good quality, minor light leak on the zipper. No longer available but posted it to give feedback on cheap tents vs the 100$+ ones. Personally I think they all come from the same place.

Np, we've all been there! I should've mentioned that airflow in the tent is really good for mold prevention.

Also, if you can, go for 3x3x5-7, it's always good to account for utilities you might need in the tent, (fan, small dehumidifier for the flower stage) and the height consumed by lighting/pots.

Edit: you don't even need 3x3, in the winter I use this for 2 plants

This is what I use: https://www.amazon.com/dp/B00132G102/

Get a big bottle of the General Hydroponics pH 7.0 calibration and storage solution. You need to rinse the electrode with clean water after every use and change the storage solution regularly (1-2 weeks), but if you keep up with the maintenance they'll stay accurate and last quite awhile.

Those drops suck IMO, same with the strips. I feel that the nutrient ions somehow interfere with the reaction on the strips, and you get color interference like you said with the drops. A glass electrode pH meter is what you want.

Proper pH is fundamental to the plant thriving just like light, temperature, humidity, etc. because it's so closely tied to root health and nutrient absorption. It's worth paying close attention to.

I've coded these posts to upload automatically every week. hope you enjoy the timelapse!

I like Silica Blast on Amazon. I've used it for multiple grows now and it's only helped. Makes the leaves stand up really straight I find which is always good when you're trying to maximize how much light gets to all the leaves.

No worries!

This is actually my first grow with it. It’s just a cheap one from amazon

https://www.amazon.ca/dp/B0743F4532?psc=1&ref=ppx_pop_dt_b_asin_title

It works great for what it is, but it won’t be my long term solution.

Thank you!

Ya the confusion is the picture in the Amazon add doesn't match the size you selected. The size you've selected is right but the tent pictured in the amazon post is like 4'x8'x8'

You've got the right size tent picked though you might want to consider a different seller on Amazon. Plus the one you've selected is overpriced.

Monterey Garden Spray. This stuff kicks their ass. Apply whole plant (don't forget underside of leaves and stems) as well as the top of your soil. Apply before lights off. Then repeat the process 3 days later. Should take care of it real easy.

Nice. You going with Alibaba QBs or HLG? Have you used these for temp/humidity? https://www.amazon.com/dp/B01N56KEU6/ref=cm_sw_r_cp_apa_i_ODHlDbV3P9ZGP
I was thinking about running my inline fan and a small space heater (winter grow in wood stove cabin) off the temperature controller and then humidifier/dehumidifier off the humidity control.

That's kind of high. Do you have intake and exhaust fans set up? If you already do, I'd consider a supplement to help it do better in higher temperature.

I think you’re “done” with this bud. Many a threads are on here with “what to do” ideas.

Look to set this up ASAP and next run to get humidity in the 45%.

If you aren’t planning on getting a bigger tent I would stick with a 4” exhaust and a 4”/6” carbon filter. Here’s the link for the fan and one for the filter . I use a bigger fan and filter personally, but that’s because I plan on getting a bigger tent after my third or fourth grow. Based on the dimensions of your tent this should be a solid setup for you even if you go up a bit in the future.

Some on Amazon that are 6 for $60.

When I had Thrips it was more silver. Slowly turn the leaf over and look at the back, you should see a little yellow worm like bug. That's the thrip. If you see that, buy this Monterey Garden Insect Spray with Spinosad Concentrate 16oz and spray the fuck out of the whole plant at the start of lights out. When I say spray the fuck out of it, I mean cover that from head to toe bud and all top and back side of the leaves. Check the next day to see if you can see any live Thrips on the back of a leaf. They should be crusty and fall out. If you don't get them all one more spray should do the trick.
